EJBCLIENT000025: No EJB receiver available for handling?

Question

I am trying to connect to a remote EJB on my local JBoss 7.2 from an executable Java application (local not on JBoss).

But I get the following error/Exception :

java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:xx-xx, moduleName:xx-xx-business-impl, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@14bc02d

    at com...ris.client.PACSServiceTest.main(PACSServiceTest.java:71)

The test remote bean TestService and its implementation is in an EAR.

Server Classes:

@Remote
public interface TestService {

    public int getX();

}

@Stateless
@Remote(TestService.class)
public class TestServiceBean implements TestService{

    @Override
    public int getX() {
        // TODO Auto-generated method stub
        return 1111;
    }
}

Client code:

final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
jndiProperties.put(Context.PROVIDER_URL,"remote://localhost:4447");

String jndiName = "ejb:orbis-dicom/orbis-dicom-business-impl//TestServiceBean!"
                  + TestService.class.getName();
logger.info(jndiName);

final Context context = new InitialContext(jndiProperties);
TestService service = (TestService) context.lookup(jndiName);

logger.info(service.getX());

jboss-ejb-client.properties:

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port =4447

Any ideas? Thanks in advance!

Solution 1

You need to keep the InitialContext referenced (it must not be garbage collected) as long as you want to access methods on the "lookup'ed" Remote EJB.

Solution 2

The same issue has been bugging me for days. I'm using Wildfly 9.0.2, but the essence should be the same. Set the property jboss.naming.client.ejb.context to false.

JBoss provides two different means for remote lookup, "remote-naming" and "ejb-client". Both are explained best at https://docs.jboss.org/author/display/AS71/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project

You are using a pure "ejb-client" approach, in which the InitialContext that the EJB proxy was looked up from is no longer valid (i.e., it was closed or gc'ed). This is what the "no EJB receiver" exception means. When the property jboss.naming.client.ejb.context is true, it indicates that InitialContext should be used for all EJB calls. Keeping a reference to the InitialContext as mentioned earlier isn't a good idea, however.

The solution is to set jboss.naming.client.ejb.context to false, which enforces EJB calls to be managed by the "remote-naming" framework. In order for this to work, you need both jboss-ejb-client.properties and jndi.properties files on your classpath (or configure programmatically). The latter should contain the following properties:

java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url=remote://localhost:4447
jboss.naming.client.ejb.context=false

Given this setup, you may even call InitialContext.close() immediately after looking up the EJB proxy (in case you cannot wait for it to be automatically gc'ed).

Solution 3

add the setting below in your client code: jndiProperties.put("jboss.naming.client.ejb.context",true);

I've seen a lot of answers (both here and in other threads) about setting different properties for the InitialContext, but this ultimately worked for me. Thanks!
